While I was at it, I replaced the lower radiator hose and fan belt. The belt proved to be a bit of a challenge. I had to remove the hydraulic pump that mounts to the front of the motor to get the belt off. It was an original belt, with a Case number, so it served it's time, 43+ years.
Also, I fixed a bolt that had broken off in the alternator, and repaired the wire to the headlights, because it had rubbed through.
